Key Findings
The ETENWOLF S3 Cordless Tire Inflator completed a full-discharge thermal stability test at 35 psi load, with results recorded for reference only against internal standards. The cylinder-to-air-hose junction registered the highest temperature across both samples, peaking at 97.6 °C on unit S3-7#.
- Test standard: Internal standard (thermal stability evaluation)
- Load condition: 35 psi, run until battery fully discharged
- Samples tested: 2 units — S3-7# and S3-8#
- Ambient temperature: 27.7 °C
- Highest temperature recorded: 97.6 °C at the cylinder-to-air-hose junction (S3-7#)
- Highest temperature rise recorded: 69.9 K at the cylinder-to-air-hose junction (S3-7#)
- Verdict: For reference only (■供参考)

Test Procedure
- Pre-test: Record ambient temperature (initial environmental temperature). Confirm both sample units (S3-7# and S3-8#) are at ambient equilibrium before testing.
- Setup: Attach Type-K thermocouple probes to all designated measurement points: motor, cylinder, battery, cylinder-to-air-hose junction, and air hose tail knurled section.
- Load application: Set pressure load to 35 psi.
- Run: Power on the sample under the 35 psi load and allow it to run continuously until the battery is fully discharged.
- Data collection: Continuously log temperature readings at all measurement points throughout the run. Detailed time-series data recorded on the companion sheet (温升采集数据).
- Post-test: Record peak temperature and calculate temperature rise (ΔT in Kelvin) for each measurement point per sample.
Acceptance criteria: This test was conducted against the internal standard for evaluating thermal stability and potential overheating risk. Results are classified as Pass, Fail, or For Reference Only based on engineering judgment.
Test Data & Results
| Sample No. | Parameter | Motor | Cylinder | Battery | Cylinder-to-Air-Hose Junction | Air Hose Tail Knurled Section | Ambient Temp (°C) |
|---|---|---|---|---|---|---|---|
| S3-7# | Peak Temperature (°C) | 50.7 | 59.6 | 54.5 | 97.6 | 39.6 | 27.7 |
| S3-7# | Temperature Rise (K) | 23.0 | 31.9 | 26.8 | 69.9 | 11.9 | — |
| S3-8# | Peak Temperature (°C) | 49.0 | 58.4 | 57.1 | 89.3 | 44.9 | 27.7 |
| S3-8# | Temperature Rise (K) | 21.3 | 30.7 | 29.4 | 61.6 | 17.2 | — |
Observations: The cylinder-to-air-hose junction consistently produced the highest temperatures on both units (97.6 °C / 69.9 K rise on S3-7#; 89.3 °C / 61.6 K rise on S3-8#). The motor and cylinder bodies showed moderate thermal rise. The air hose tail knurled section remained the coolest measurement point.

Frequently Asked Questions
What does the temperature rise test measure on the ETENWOLF S3 tire inflator?
The temperature rise test measures how much each key component — motor, cylinder, battery, cylinder-to-air-hose junction, and air hose tail knurled section — heats up during continuous operation under a 35 psi load until the battery is fully discharged. It evaluates thermal stability, heat dissipation performance, and potential overheating risk using Type-K thermocouples.
What was the highest temperature recorded during the S3 thermal test?
The highest temperature recorded was 97.6 °C at the cylinder-to-air-hose junction on unit S3-7#, representing a temperature rise of 69.9 K above the ambient temperature of 27.7 °C. Unit S3-8# reached a peak of 89.3 °C at the same point, a rise of 61.6 K.
Why are the S3 thermal test results classified as “For Reference Only” rather than Pass or Fail?
The test was conducted against an internal standard designed to characterize thermal behavior rather than certify compliance with a fixed threshold. The “For Reference Only” classification means the data is used by engineers to assess design margins, guide thermal management decisions, and benchmark future design iterations — not to determine regulatory conformance.
Where can I find the full time-series temperature data for the S3 thermal test?
The complete time-series temperature data collected during the test run is available in the companion sheet (温升采集数据) of the same report file. See the Related Products section below for the direct cross-link.
